What did you find for flow measuring?
"Franz Eckert" wrote in message . dk... Hi Larry. Actually i have found a flow measuring device, rather cheap too. But i should have pointed out that i was in search for the schematics for the read out device. So what i need is a schematic that i can make a digital or analog read out of the impulses from the flow sensor. And it would be nice if it was not Dependent on a notebook. Nice links, but 'damn' they are expensive :-) Wkr Franz "Larry" skrev i en meddelelse ... "Franz Eckert" wrote in . dk: Maybe some of you gurus have an inexpensive idear of how to make a flow meter that can measure the usage af gas to the engines. I don't really care if it is analog or digital, as long as i can built it myself :-) The medical profession has a clear plastic flowmeter that's about 3" in diameter with a red ball that the fluid running through it rotates around the tube. It's a positive flow meter in that the ball just fits the round tube and the tiniest flow of liquid shows up as a rotation of the ball. I have no idea where you'd get it, but I'm sure any nurse or hospital supply person could point you to the right company. It would be very simple to put a light on one side of this tube and a photocell on the other (OK, IR LED and photo IC is more complex and up-to- date). Every time the ball comes around the loop, it would cut the light so you could TIME the ball's rotation around the loop, which on the tube is calibrated in cc/hr or minute for the nurse to count. The time measured would be easily converted to litres/hour or gallons/minute for your display. The pulses could simply be fed to a serial port on a PC or notebook already in use with a simple program monitoring the port's data-in and using the PC's timer functions. How's that?....(c; Americans, a lazy, sloven lot to be sure, would use: http://www.asenashop.com/ivn/pr-0/9286.html or http://store.wmjmarine.com/s3fw022u1.html or http://www.consumersmarine.com/produ...l.cfm?i=380020 or http://www.marineparts.com/partspages/FLOSCAN/FLO1.htm They all run on a little wheel that rotates as the fuel pushes it around passing through it. A magnet senses the wheel's movement and converts each vane into a pulse for measurement... -- Larry |

Hi there.
Goto www1.uk.conrad.com and search for component number 187151 - 14 That should do the trick, don't you think? Wkr Franz "johnhh" skrev i en meddelelse ... What did you find for flow measuring?

If you feel nostalgic, feel free and change my oil in my 671s or clean
out my breathers. I won't even charge you for the experience!!!! Larry wrote: "Franz Eckert" wrote in . dk: That should do the trick, don't you think?

Had a 6-71 hooked to a big DC generator aboard USS Everglades AD-24 to power my calibration lab through a DC to 60Hz m-g set, 25KW? Something like that. Great engine. Uncle never complained about all the hours I put on her...(c; Er, ah, I'll pass on the oil changing....thanks. -- Larry |

I hate to break it to you.. but Detroit diesel NEVER made a 9V92 engine.... Maybe it was a typo for 8V92..... Bruce in alaska -- add a 2 before @ |

Okay Larry, let me tell you my story.
Here in Demark we pay so many taxes, that we have to do everything ourselves :-) For 5 years ago i bought a old military coast control boat. 30 feet, 5 tons, two Mercedes 180 installed. I was happy, my own boat, yappiiii. But then the engines began to fail, they were old, very old. I took out one, and send it for a complete overhaul. That costs me in the area of 2000 Dollars. NO MORE i said. So when the second began to fail, and was due to a overhaul, i simply took out the old engines, and then started to remove all the old wood that was rotten. One thing lead to another, ans soon i was standig there with a 30 foot open rowboat. Everything was rotten. I had to reinforce the bow with 10 layers og glasfiber, because there was absolutely no wood underneath. At the same time i removed about 15 pipes through the hull, they were of no use, and i don't know what they ever where there for. So i started looking around for some suitable engines (cheap), and found two Golf Diesel 1.6 liters on the Internet, they costs me about 80 $. It took me (and a friend) about 2 months making my gears fit on the new engines, but finally we succeded. Then i started rebuilding the entire boat, completely new interior, and new top. It has taken me almost 3 years, and i am still not done yet. The gears were of the type with a loooong gearchange handle, so usual morse cable would not hold for long ( i had already broken 3). So i thought that maybe air pressure and one air piston on each gear maybe could do the trick. And despite what everybody told me, i made it work. I also had to make a new fuel tank. There were two in the old days, but they flowed from one tank to the other, in a 1/4 inch hose, that took about 1 hour before they leveled out. The fuel outlet was in the bottom of the tank, so my filters keept getting real dirty. Almost everything was made by peoble that had absolutely no idear about what they were doing. So redoing the boat was a good idear, it has become much stronger and reliable, and now i know exactly how everything is put together. So now i can enjoy sailing again, but there still needs a lot of finishing touch to the boat. Tell me, just to make me real ****ty overhere, what is the comon price on two used disel engines, around 70-100 HP, with gear and everything? If you like i can send you a link to some pictures that illustrates me rebuilding the boat. Wkr Franz "Larry" skrev i en meddelelse ...

If you like i can send you a link to some pictures that illustrates me rebuilding the boat. Wkr Franz Yo, Franz Would love to see that! The last madman ist born yet - I thought it was me.... I have started out on a 28-footer GRP fishing boat hull, sawn in 3 pieces (and then some)to get decommission pay from the guvinmint. I now have the MF aligned and put together - almost all holes patched, filled, ground etc - and now it awaits osmosis coating on a totally raw bottom. But I get off the track.... We're talking engines here... Well at the local scrapyard I could get a renovated drive line 105 HP marine diesel engine with gear, driveshaft, stern tube and prop for roughly 10,000 USD + 25% taxes (The VAT has never caught on in Jutland, however). And we are talking about us normal, half-broke guys, right? So good & wise people said: Since running a diesel with a propeller means 75% output on the prop, and since the load on the engine corresponds to constantly driving uphill, go for someting big and solid (I need 1.5 t. of ballast anyway) and prefreably 6 or 8 cylinders to minimize vibration. So my choice of engine turned out to be a Nissan diesel (Patrol style) 6-cyl. 130 Hp about 15 yr. old diesel. reputed to be indestructible. Of course I have to construct a watercooled exhaust flange in order not to get an exhaust that's too hot to handle, and provide it with a fresh water cooling system (Sea water won't do for a number of reasons). No sweat - almost. But I got the first one for free - we will test run that one during the winter and if it turns out OK, we drop it in. The engine room is made with ample space for a bigger engine, though. But the bottom line of this long yarn is that I can get a renovated and tested Patrol engine for roughly 2000 USD. The Golf diesel is a good one - but beware the cooling! And anyway it's better to lose an engine than THE engine :-) Good Luck Ole |

I bought a used Perkins 4-108 with all controls and transmission from someone on the rec.boats.cruising newsgroup in North Carolina for $US1200 with 700 hours on it. It's been powering Lionheart ever since. Runs great. It's only 50hp, though, but that should give you some ideas. http://www.tadiesels.com/used.html#MENG That should give you an idea of what they're charging on this side of the pond. -- Larry |
